Data Module (``PsychiatryNLPKit.data``)
========================================

Data containers for organizing clinical text and managing pre-computed linguistic features.

The ``TextData`` class is the central data structure — it holds named sections of text,
lazy-loads NLP models on first access, and caches all computed features (POS tags,
embeddings, constituency parses) so multiple analyses share the same computation.
